The San Pedro is one of the few positively identified examples of the classic galleon ship type used in New World trade. The remains of the San Pedro include a 90 ft. long by 30 ft. wide ballast mound and hull timbers that are covered by sand and marine vegetation. Seven replica concrete cannons and an iron anchor from another 1733 wreck have replaced the originals which were removed by treasure hunters in the 1960s. An underwater plaque identifies the site and its status as an Underwater Archaeological Preserve.

Questions for Diagram 2

1. Why do you think the replica cannons were added to the site? What happened to the originals?

2. What differences do you see between the ballast piles of the Urca de Lima and the San Pedro? Based on what you learned in Readings 2, 3, and 4 why might this be the case?

3. Why might marking the site with an underwater plaque be important?
